Description

Technical Field

[0001] This utility model relates to the field of steering system technology, specifically a pre-positioning device for a steering gear ECU heat sink. Background Technology

[0002] During the assembly of the steering gear ECU heat sink, the incoming plastic box for the heat sink is affected by the injection molding material, shrinkage rate, and free dimensions without special tolerance requirements. In actual production, the heat sink has a certain shape and position deviation in the material box. In order to meet the precise positioning requirements of subsequent processing and assembly processes, the robot will first pick up the heat sink from the material box and place it on the pre-positioning fixture for initial positioning, and then pick up the heat sink from the pre-positioning fixture and place it on the precision positioning rotary table for subsequent processes. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, this utility model provides a pre-positioning device for the steering gear ECU heat sink, which can accommodate the shape and position deviations of the injection molding box. By positioning once, it ensures that the robot arm grasps the same position every time, avoiding part scrapping and equipment failure caused by the robot arm misplacing parts, and improving the stability of the processing.

[0004] To achieve the above objectives, a pre-positioning device for a steering gear ECU cooling plate is designed, comprising a side plate, a cylinder protection plate, an indexing plate rotary cylinder, a transition plate, and a base plate. The side plate is characterized in that: the top of the side plate is connected to the bottom of the cylinder transition plate; the cylinder transition plate is equipped with an indexing plate rotary cylinder; the top of the indexing plate rotary cylinder is connected to the bottom of the transition plate; the top of the transition plate is connected to the base plate; and a first pre-positioning guide pin and a second pre-positioning guide pin are respectively connected to the base plate.

[0005] The base plate is connected to a first pre-positioning guide pin, a second pre-positioning guide pin, and a support pin, and the first pre-positioning guide pin, the second pre-positioning guide pin, and the support pin are distributed at 60°. Two precision positioning pins are provided on one side of the first pre-positioning guide pin and the second pre-positioning guide pin, and the bottom of the precision positioning pin is connected to the base plate through a precision positioning pin base.

[0006] The base plate is connected to the top of the transition plate by several nuts.

[0007] The first prepositioning guide pin is a cylindrical structure, and the upper end face of the first prepositioning guide pin is a circular flattened structure. The height of the first prepositioning guide pin is 35mm.

[0008] The second prepositioning guide pin is a cylindrical structure, and the upper end face of the second prepositioning guide pin is a 60° chamfered conical structure, and the height of the second prepositioning guide pin is 35mm.

[0009] Cylinder protection plates are provided around the indexing plate rotary cylinder, and the bottom of the cylinder protection plates is connected to the cylinder transition plate.

[0010] The bottom of the side plate is fixedly connected to the working platform of the processing equipment.

[0011] Compared with the prior art, this utility model provides a pre-positioning device for the steering gear ECU heat sink, which can accommodate the shape and position deviation of the injection molding box. This device is suitable for the positioning component design of heat sink parts. Therefore, in the automated production process, the device for automatically positioning heat sink parts ensures that the robot arm grasps the same position each time through one positioning, avoiding the scrapping of parts and equipment failure caused by the robot arm placing parts in the wrong position, and improving the stability of the processing process.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] like Figures 1 to 4 As shown, the top of the side plate 6 is connected to the bottom of the cylinder transition plate 5. The cylinder transition plate 5 is equipped with an indexing plate rotating cylinder 3. The top of the indexing plate rotating cylinder 3 is connected to the bottom of the transition plate 2. The top of the transition plate 2 is connected to the base plate 1. The base plate 1 is connected to the first prepositioning guide pin 7 and the second prepositioning guide pin 8 respectively.

[0018] The base plate 1 is connected to the first prepositioning guide pin 7, the second prepositioning guide pin 8, and the support pin 9, and the first prepositioning guide pin 7, the second prepositioning guide pin 8, and the support pin 9 are distributed at 60°; two precision positioning pins 10 are provided on one side of the first prepositioning guide pin 7 and the second prepositioning guide pin 8, and the bottom of the precision positioning pin 10 is connected to the base plate 1 through the precision positioning pin base 11.

[0019] The base plate 1 is connected to the top of the transition plate 2 by a number of nuts 12.

[0020] The first prepositioning guide pin 7 is a cylindrical structure, and the upper end face of the first prepositioning guide pin 7 is a circular flattened structure. The height of the first prepositioning guide pin 7 is 35mm.

[0021] The second prepositioning guide pin 8 is a cylindrical structure, and the upper end face of the second prepositioning guide pin 8 is a 60° chamfered conical structure. The height of the second prepositioning guide pin 8 is 35mm.

[0022] A cylinder protection plate 4 is provided around the indexing plate rotary cylinder 3, and the bottom of the cylinder protection plate 4 is connected to the cylinder transition plate 5.

[0023] The bottom of side plate 6 is fixedly connected to the working platform of the processing equipment.

[0024] The first pre-positioning guide pin 7 and the second pre-positioning guide pin 8 have two different structural designs. The first pre-positioning guide pin 7 is a 35mm high cylinder with a circular flattened structure on the upper end. The second pre-positioning guide pin 8 is a 35mm high cylinder with a 60° chamfered top surface. Utilizing the chamfered end face and central hole design on the heat sink part, when the robot arm grips the heat sink workpiece and reaches directly above the pre-positioning fixture, it releases the gripper. As the heat sink workpiece descends freely, it first contacts the first pre-positioning guide pin 7. Since there is approximately a 2mm gap between the upper surface of the first pre-positioning guide pin 7 and the arc surface on the heat sink workpiece, when the first pre-positioning guide pin 7 is inserted into the arc surface of the heat sink workpiece, the cone surface of the upper surface of the second pre-positioning guide pin 8 corrects and guides the circumference of the heat sink workpiece. During the free fall of the housing, after the position of the heat sink workpiece is corrected by the pre-positioning structure, the two precision positioning pins 10 are guided into the positioning holes of the heat sink workpiece to complete precise positioning. The three support points—the first pre-positioning guide pin 7, the second pre-positioning guide pin 8, and the support pin 9—are not collinear and are distributed at a 60° angle, ensuring that the heat sink workpiece is placed on a stable plane, thus achieving high efficiency and continuity in subsequent production processes.
